According to 2022 statistics published by the US EPA, enteric fermentation (a digestive pathway that produces gasses in the gut) by cattle accounted for around 3% of total US greenhouse gas emissions when converted to carbon dioxide equivalents. We spoke with Dr. Glenn Duff, from New Mexico State University to learn more about the research he and his team are conducting to measure gas fluxes and emissions from cattle in pursuit of improving efficiency and lowering emissions from this sector.
